Is an EPC
a Legal Requirement?

When EPCs are legally required in the UK

EPC requirements split across three main scenarios in UK law. Each has its own legal basis, deadlines plus penalties. Understanding which applies to your situation determines the action needed.

Scenario 1: Selling a property. Under the Energy Performance of Buildings (England plus Wales) Regulations 2012, sellers must commission an EPC within 7 days of marketing the property. The EPC must be made available free of charge to any prospective buyer. The EPC rating plus a copy must be included in any sales particulars. Failure to comply leads to a £200 penalty per breach enforced by local Trading Standards.

Scenario 2: Renting out a property. Under the same 2012 Regulations plus the Minimum Energy Efficiency Standards (MEES) Regulations 2015:

• Every rental property in England plus Wales must have a valid EPC.
• The rating must be E or above (rising to C from 1 October 2030).
• The EPC must be provided to tenants free of charge before tenancy begins.
• The EPC rating must appear in property advertising.

Local authorities enforce MEES rules. Penalties up to £5,000 per breach for letting non-compliant properties.

Scenario 3: New build construction. Building Regulations require an EPC before practical completion of any new domestic or commercial building. The construction process plus Building Control sign-off are linked to the EPC issue. The new build EPC uses the full SAP methodology rather than the RdSAP simplified version used for existing homes.

Scenario 4: Major renovation. If a renovation involves more than 25 percent of the building envelope (such as significant extensions, replacement of major heating systems or substantial wall insulation), Building Regulations may require an updated EPC. Check with Building Control during planning.

EPC validity plus reuse. EPCs last 10 years from the date of issue. The same EPC can be used for multiple sales, tenancies plus other transactions during the 10-year window. After 10 years the EPC expires plus a new assessment is needed.

Limited exemptions to the EPC requirement:

• Listed buildings. Where compliance with minimum energy performance requirements would unacceptably alter character or appearance. Not automatic. Each property assessed individually.
• Places of worship plus religious buildings. Used for religious activities.
• Temporary buildings. Used for less than 2 years.
• Industrial sites, workshops plus non-residential agricultural buildings. With low energy demand.
• Standalone buildings. Total useful floor space less than 50 square metres.
• Buildings due for demolition. If the seller has applied for relevant planning consent or demolition consent.
• Holiday lets. Used for less than 4 months per year.

Penalties plus enforcement:

• Trading Standards enforces EPC requirements for sales. Penalty £200 per breach for residential.
• Local authorities enforce MEES rules for rentals. Penalties up to £5,000 per breach plus public listing on the PRS Exemptions Register.
• Building Control enforces new build EPC requirements as part of project sign-off.
• Persistent non-compliance can lead to additional Notice of Intent plus higher penalties.

Northern Ireland plus Scotland. Each devolved nation operates its own EPC regulations. Scotland requires EPCs for sales plus rentals under the Energy Performance of Buildings (Scotland) Regulations 2008. Northern Ireland uses the Energy Performance of Buildings (Certificates plus Inspections) Regulations (Northern Ireland) 2008. Both systems are similar to England plus Wales but administered separately.
